Comment 13 for bug 1394368

I got pointed here from:

As suggested also above I copied both these files from Windows' (Program Files\Common Files\QCA-Bluetooth) to Ubuntu's /lib/firmware/ar3k -folder:
- AthrBT_0x11020100.dfu
- ramps_0x11020100_40.dfu

With these files in place the Bluetooth is working on both of these experimental kernels: (for more info see bug 1425252, link above)
- 3.18.0-14-generic #15 SMP Fri Feb 27 18:38:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
- 4.0.0-040000rc1-generic #201502261652 SMP Thu Feb 26 16:56:29 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Bluetooth still does not work on published kernels:
- 3.16.0-31-generic #41~lp1352821v1 SMP Fri Feb 20 20:52:34 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux OR
- 3.16.0-30-generic #40-Ubuntu SMP Mon Jan 12 22:06:37 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Now I'm also facing the same Bluetooth works / does-not-work after reboot issue. At least bluetooth mouse doesn't automatically reconnect after restart. Instead mouse text "flickers" in Bluetooth GUI screen. After clicking "ON" button (on bluetooth gui) for several times the bluetooth mouse might reconnect - or not.

Also if I click "Connection ON" to mouse from underneath the Bluetooth icon on system tray it seems to try to get the connection establihed as the bluetooth icon's lock symbol goes ON and OFF repeatedly.

System: Acer Aspire V3-371-79RJ and Ubuntu 14.10.
